For syncing across multiple devices and being potentially available on the web portal or from the browser extension check out Saas Pass if that’s what you might be interested in.
Disclaimer: worked on it
Agreed. It's been buggy enough that I've been looking for an alternative to migrate things to. Perhaps I'll try Obsidian!
Let me know if you need any help :)
In the app settings you can also find the email to contact me directly!
Cheers
No specific reason to assume Obsidian is better, but, its annoying enough that it turned Authy from something that seamlessly "just works" into something which I feel like i'm fighting with.
